Embodiment Construction
[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0034] see in conjunction Figure 1-Figure 3 Shown is Embodiment 1 of the design method of the deflector of the present invention. The deflector design method in the present embodiment comprises the following steps:
[0035] Step S1, according to the shape and structure of the grille at the front end of the vehicle cabin and the deviation between the cooling module and the grille in the forward projection position, determine the preliminary structure of the deflec...

The invention discloses a flow guiding plate designing method which comprises the following steps that according to the model and the structure of a car cabin front end grid and the deviation situation of a cooling module and the grid at a forward-direction projection position, an initial structure of flow guiding plates is determined, and the initial structure at least comprises the shape, the number and the arranging positions of the flow guiding plates; according to the air flow backflow route in the cabin under an idling or low-speed working condition of a car, the initial structure is adjusted, the assembling positions of the flow guiding plates are determined, and the air flow backflow route is blocked; the flow guiding plates are optimized, and a cooling module and cooling air amount meet the requirement of a car cooling system; and the arrangement between the flow guiding plate and the cooling module is optimized, and accordingly pneumatic resistance in the car cabin is lowered. The invention further discloses the flow guiding plate structure designed with the flow guiding plate designing method. According to the flow guiding plate designing method and the flow guiding plate structure designed with the same, hot gas backflow can be avoided, the air inlet amount of the cooling module is increased, and pneumatic resistance can be lowered.
Description
technical field [0001] The invention relates to the field of heat management of a complete automobile, in particular to a design method of a deflector and a structure of the deflector designed by the design method. Background technique [0002] Vehicle thermal management and aerodynamic performance are one of the most important performances of automobiles, which are related to automobile driving reliability, economy and power performance, and are important technical problems in the process of automobile development. In the process of automobile design, unreasonable design of the front end of the cabin may easily cause idling backflow, leakage and turbulent flow, resulting in low thermal efficiency of subsystems, heat accumulation or overcooling in the cabin, affecting the performance and life of the vehicle; at the same time, the optimization of aerodynamic performance It is an important way to reduce vehicle resistance and reduce fuel consumption. [0003] In the prior art...
